Yes I go into Preferences, RealTracks and use the Custom location to point to where the RealTracks are.
The RealTracks are on the Hard drive of the desktop.
Windows 10 see the folder and can open it.
In BIAB, when I use Options/Préférences I can see the folder RealTracks but BIAB anwser: "The folder "\\PC-BUREAU\RealTracks" does not exist"
PC-BUREAU is the name of the desktop.

I hope you can understand what I'm wriiting because I am french and my English is really bad.
Thank you
